China's National Energy Administration (NEA) and State Oceanic Administration (SOA) jointly implemented the Interim Measure on the Management of Offshore Wind Farm, regulating every aspect of offshore wind development. The 38-related articles stipulate that offshore wind farms concessions must be allocated through a competitive public bidding process taking into account offered prices, technical abilities and forecasted performance results. Developers must be Chinese-funded companies or Sino-foreign joint ventures (with at least 50% Chinese ownership).The regulation also imposes a two year inactivity period from the end of the tender process before any construction work can starts.
